According to Melvin Mughal, the decline in performance was due to the recent upgrading of the system iOS two iPhones. It arrives to resolve some of the bugs that can give access to your information to malicious hackers. A fall in performance was expected and this should happen with computers and smartphones of other brands.
The Dutchman used the performance measurement app Geekbench to register the speed of an 6 iPhone before upgrading, such as iOS 11.1.2, and then with iOS 11.2.2. According to the results, there was a decrease of 41% in tasks performed with a single processing core and 39% in those that use more than one.
However, as Mughal acknowledges, it is difficult to attribute this drop in performance to just the software update. It is also possible that the poor performance in terms of speed is one of the consequences of limiting battery performance that Apple admitted earlier this month to purposely practice on older models of its products.
"While these are not the best news in the world, security updates are a necessary evil'. Any performance outages that your devices may experience will not be worth the risk of being hacked. Your safety should always come first, "concludes the Dutchman.
